Update 2: A complete look at ‘Smart Lock’ on HTC One M8 with lollipop

Smart Lock is one of the new ways of handling lockscreen in Lollipop, simple that you’ve got Trusted devices etc that gives you quick entry into the phone.

This have been updated again since Smart lock now supports a fifth method called Trusted Voice.

Edit: Telia, as shown on some screenshots, is the name of the Swedish network my phone is on.

First you need to enable Smart Lock

This about when you have updated to Lollipop, it might already be there by default after a factory reset.

This all happens under Settings > Security

You NEED to enable a lockscreen with a password, pattern or PIN first or the rest of the steps will simply not work. I use Pattern myself since that is what I prefer. Smart Lock requires this.

If Smart Lock turns on. Then you’re done. If it doesn’t, you need to keep on reading.

Then you go down to Trust Agents that you find right under Advanced. Inside there you will find Smart Lock, simply enable that. And step back into Security where you now will have Smart Lock.

Then what?

Smart lock consists of 5 different types of Trusts. Which can be used in combinations.

1. Trusted Face

Make sure that Smart lock is enabled

Follow the set up guide for Trusted Face under Settings >Security > Smart lock. It can be a little fiddly to get it right, just try until it’s done.

That’s it, but don’t expect to see much of this when using it on the lock screen.

What you see below is the 3 states of the unlock “pad lock” or what to call it. When you first turn the screen on, it will turn into a user icon type symbol, that means that it’s looking for your face (or have your face in “target”). You can now just swipe up to unlock your screen, assuming that you’re looking at your phone at the proper distance. Sometimes you need to wait for the unlocked pad lock symbol. If the pad lock is locked, it means that it didn’t find your face or simply failed. Swiping up will bring you to your regular PIN/password/pattern. This WILL take a bit of practice.

2. Trusted device

This is part of Smart Lock which is one of the coolest things in Lollipop.

Add a trusted device to keep this device unlocked when connected

That’s how Google describes is, and is pretty much what it does and how it works.

Will focus on Bluetooth now since it’s what most people got, and it’s the easiest way of doing this. I will use my desktop computer as a trusted device, I would use a smartwatch as it if I had one…

If the bluetooth device you want to use is not paired and connected

Settings > Bluetooth, where you turn it on and scan for devices. Make sure that the bluetooth device you’re pairing with is in pairing mode. That depends on the device used, and I will not cover that here.

When the device is paired and connected, you will see an unlocked pad lock icon in the notification field that asks you if you want to add the newly connected device as a Trusted device.

Ok, done all that. How do I know that it works?

The only really tell is that the pad lock on the lockscreen it unlocked. Now when you’re in reach and connected with the bluetooth device, the padlock will unlock and let you just swipe the lockscreen open. If you’re outside it’s reach, you need to enter you pin/password/pattern.

3. Trusted Place

Simply that you just have to swipe your phone open when you’re at a certain address. Like Home or Work.

This requires that Smart Lock is enabled, or it will simply not work.

Make sure Smart Lock is on

This all happens under Settings > Security

You NEED to enable a lockscreen with a password, pattern or PIN first or the rest of the steps will simply not work. I use Pattern myself since that is what I prefer. Smart Lock requires this.

If Smart Lock turns on. Then you’re done. If it doesn’t, you need to keep on reading.

Then you go down to Trust Agents that you find right under Advanced. Inside there you will find Smart Lock, simply enable that. And step back into Security where you now will have Smart Lock.

Enable Trusted Places

Open Settings > Security > Trusted places

If you got set Home and Work places in the Settings of Google Mapsapp, you can simply enable those. If they’re greyed out despite having set Home & Work address, open Google Maps and redo at least one of them under “Your places”. You might have to play around with it a bit. Or simply add it using Customised places, where you just tap on Add trusted place and simply enter the address.

That’s pretty much it. Now when you turn screen on, the pad lock should be unlocked where you are at or near a Trusted place. So, just swipe up to unlock without having to enter a pattern or pin/etc. And, when you’re outside a Trusted place you simply gets asked to enter your pattern/etc.

4. On-body detection

On-body detection simply keeps your phone unlocked as long as you have it on you.

First you need to make sure that you have the very latest Google Play services updates. On my devices it’s 7.0.97 (1791429-438). It will just update itself, sometimes it asks for it. If the update haven’t reached your phone yet, you can always go looking for it atapkmirror.

And: this seems to work on any device with Lollipop and the correct updated Google Play services.

Next step

It seems that it have a “grace” period where it just unlocks when you just have set it down.

5. Trusted Voice

As always. Regular EU One M8. With 5.0.1 and everything (play store services) updated to the latest versions. I think that this is a more gimmicky than the other Smart Locks, but we all like different things.

First you need to make sure that Smart lock is active

If there is no Smart Lock even with the correct lock screen set, you need to follow THIS

Yes, I have done that. But, Trusted voice is greyed out!

If you don’t have English (US) as a primary “voice input language”, this will never ever work. Currently it’s only fully supported by English (US).

English (UK) as primary

English (US) as primary

So, go to Settings > Language & keyboard > Voice input. Where for me Enhanced Google services is selected. Tap that. UnderLanguages you find English (US) where you tap and hold that language. This will set it as primary voice input language. You can have various combos of languages but English (US) need to be Primary language or this will not work.

And, that is pretty much it. To unlock you simply use “ok google”. Which may or may not work. Have fun!
